22 **What it does**
|
|
|
23
|
|
|
24 This program generates plots and computes table matrix of second moments, p-values, and test orientations at multiple scales for the correlation between the occurrences of features in one dataset and their occurrences in another using multiscale wavelet analysis technique.
|
|
|
25
|
|
|
26 The program assumes that the user has two sets of DNA sequences, S1 and S1, each of which consists of one or more sequences of equal length. Each sequence in each set is divided into the same number of multiple intervals n such that n = 2^k, where k is a positive integer and k >= 1. Thus, n could be any value of the set {2, 4, 8, 16, 32, 64, 128, ...}. k represents the number of scales.
|
|
|
27
|
|
|
28 The program has two input files obtained as follows:
|
|
|
29
|
|
|
30 For a given set of features, say motifs, the user counts the number of occurrences of each feature in each interval of each sequence in S1 and S1, and builds two tabular files representing the count results in each interval of S1 and S1. These are the input files of the program.
|
|
|
31
|
|
|
32 The program gives two output files:
|
|
|
33
|
|
|
34 - The first output file is a TABULAR format file representing the second moments, p-values, and test orientations for each feature at each scale.
|
|
|
35 - The second output file is a PDF file consisting of as many figures as the number of features, such that each figure represents the values of the second moment for that feature at every scale.

|
41 **Note**
|
|
|
42
|
|
|
43 In order to obtain empirical p-values, a random perumtation test is implemented by the program, which results in the fact that the program gives slightly different results each time it is run on the same input file.

|
|
49 Counting the occurrences of 5 features (motifs) in 16 intervals (one line per interval) of the DNA sequences in S1 gives the following tabular file::
